[First Embodiment]
FIG. 1 is a schematic vertical cross-sectional view showing a sheet cutting machine and a sheet processing apparatus including the slitter of the present embodiment. The sheet processing apparatus 1 includes a paper feeding unit 11 having a paper feeding tray 111 and a paper discharging unit 12 having a paper ejection tray 121 at both ends of the apparatus main body 10. A transport path 22 is formed from the paper feed unit 11 to the paper discharge unit 12 by a transport unit 20 composed of a large number of pairs of rollers 21. The transport unit 20 transports the sheets 100 one by one in the direction of the arrow Y from the paper feed unit 11 to the paper discharge unit 12. In the transport direction indicated by the arrow Y, the paper feeding section 11 side is referred to as "upstream side", and the paper ejection section 12 side is referred to as "downstream side". The transport path 22 is provided with processing sections 3A, 4A, and 5A from the paper feed section 11 side through a transport correction section, an information reading section, a reject section, and the like (not shown). Here, the processing portion 3A is a sheet cutting portion that only performs processing for cutting the sheet at an arbitrary position in the width direction along the transport direction Y. The processing unit 4A is, for example, a crease processing unit that creases the sheet at an arbitrary position in the width direction along the transport direction Y, and the processing unit 5A is, for example, a lateral cutting unit that cuts the sheet along the width direction of the sheet. It is a sheet cutting part. The "width direction" is a direction X orthogonal to the transport direction Y. When viewed from the upstream side to the downstream side, the right side in the width direction is referred to as "right side" (or simply "right"), and the left side in the width direction is referred to as "left side" (or simply "left"). .. The processing units 4A and 5A may be processing units that perform any other type of processing. Further, the sheet cutting portion may be provided on at least one of the processing portions 4A and 5A, and in that case, the processing portion 3A may be a processing portion that performs any other type of processing. Further, two or more processed portions can be provided in any number.

Further, the sheet processing apparatus 1 includes a control unit 6 for controlling the operation of the entire apparatus in the apparatus main body 10. The control unit 6 is realized by a CPU, ROM, RAM, and the like. An operation panel 60 is connected to the control unit 6. Further, the sheet processing apparatus 1 has a trash can 110 at the bottom of the apparatus main body 10 for accommodating chips (including bleeding chips) generated by processing the sheet.

FIG. 2 is a view of the sheet cutting machine 3 provided in the processing portion 3A as viewed from the upstream side in the transport direction. The sheet cutting machine 3 includes six slitters arranged in the width direction. There are two types of slitters, a right-type slitter 7A and a left-type slitter 7B. The right-type slitter 7A and the left-type slitter 7B differ only in that they have symmetrical structures. The number of slitters included in the sheet cutting machine 3 is not limited to six, but one or more is arbitrary, and in the present embodiment, the maximum number is 10.

(Specific configuration)
FIG. 3 is a perspective view of the right-type slitter 7A as viewed from slightly above on the upstream side. 4 to 9 are six views of the right type slitter 7A, FIG. 4 is a right side view, FIG. 5 is a front view seen from the upstream side, FIG. 6 is a left side view, and FIG. 7 Is a rear view, FIG. 8 is a top view, and FIG. 9 is a bottom view. As shown in these figures, the right-type slitter 7A connects the upper rotary blade 71, the lower rotary blade 72, the box-shaped upper housing 75, the box-shaped lower housing 76, and both housings 75 and 76. It has a connecting plate 77 and a bleeding waste removing member 73.

FIG. 10 is a cross-sectional view taken along the line XX of FIG. The upper rotary blade 71 is located at the right end of the upper housing 75, and is cantilevered supported by the cantilever support portion 78 on the cut surface 711 side of the upper rotary blade 71. The lower rotary blade 72 is located near the right end of the lower housing 76, and is cantilevered supported by the cantilever support portion 79 on the non-cutting surface 722 side of the lower rotary blade 72. However, the lower rotary blade 72 is located on the left side of the upper rotary blade 71. FIG. 11 is a schematic diagram of FIG. The upper rotary blade 71 is a flat blade. The right-type slitter 7A has both rotary blades 71 and 72 rotating so that the tip of the upper rotary blade 71 on the cut surface 711 side and the tip of the lower rotary blade 72 on the cut surface 721 side rub against each other. The sheet passing between 71 and 72 is cut. Incidentally, as shown in FIG. 7, the two sheet pieces 101 and 102 generated by cutting are separated by the folded portion 771 of the connecting plate 77 and pass downstream. As the upper rotary blade 71, a rotary blade having the same shape as the lower rotary blade 72 may be used.

The cantilever support portion 78 non-swingably supports the rotary shaft 741 that supports the upper rotary blade 71 with respect to the axial center 7411 by two bearings 781 and 782 arranged at intervals. As a result, the cantilever support of the upper rotary blade 71 is realized. Further, the cantilever support portion 79 non-swingably supports the rotary shaft 742 that supports the lower rotary blade 72 with respect to the axial center 7421 by two bearings 791 and 792 arranged at intervals. .. As a result, the cantilever support of the lower rotary blade 72 is realized.

Such cantilever support is achieved by satisfying conditions based on various parameters, for example, generally desirable conditions are for dimensions A, B, C shown in FIG. A / C should be increased, and B should also be increased. "A" is the width dimension supported by the bearing, "B" is the outer diameter of the bearing, and "C" is the width dimension from the edge of the bearing to the cut surface 711.

The upper housing 75 has a rectangular shape in a plan view, and the first side surface 751 (FIG. 8) faces the direction X1 (the right side in the width direction) of the upper rotary blade 71 on the non-cutting surface 712 side. The direction X2 is the direction of the upper rotary blade 71 on the cut surface 711 side, and is the width direction on the left side. The first side surface 751 forms the same plane as the non-cutting surface 712 of the upper rotary blade 71. That is, the first side surface 751 does not protrude in the direction X1 on the non-cutting surface 712 side of the non-cutting surface 712, and is located on the non-cutting surface 712 side of the cutting surface 711.

The bleeding waste removing member 73 is provided on the cut surface 721 side of the lower rotary blade 72 so as to eliminate the sheet piece generated by cutting. The bleeding waste removing member 73 includes a seat guide 731 and an operation plate 732. The seat guide 731 has a guide main body 7310 having a curved surface portion 7311 extending downward and a flat upper surface portion 7312, and a lever portion 7313 extending downward from the guide main body 7310. The curved surface portion 7311 faces upstream in the transport direction. The operation plate 732 is horizontally fixed below the lower housing 76 and has a hole 7320 through which the lever portion 7313 penetrates. As shown in FIG. 9, the hole portion 7320 has a first groove portion 7321 and a second groove portion 7322 for fixing the lever portion 7313. The lever portion 7313 is urged toward the first groove portion 7321 and the second groove portion 7322 by a spring (not shown).

The sheet guide 731 can be displaced into an exclusion mode in which the sheet piece generated by cutting is eliminated and a retracting mode in which the sheet piece generated by cutting is passed downstream in the transport direction without being eliminated. 3 and 4 show the exclusion mode, and FIGS. 12 and 13 show the evacuation mode. FIG. 14 is a perspective view of the seat guide 731 in the exclusion mode as viewed from below. The seat guide 731 is in an exclusion mode when the lever portion 7313 is fixed to the first groove portion 7321 as shown in FIGS. 9 and 14, and the lever portion 7313 is in the second groove portion as shown in FIGS. 15 and 16. When it is fixed to 7322, it becomes an evacuation mode.

In the exclusion mode, as shown in FIG. 4, since the upper end 7301 of the curved surface portion 7311 is located slightly above the cutting position H, the sheet piece generated by cutting is guided downward along the curved surface portion 7311. That is, it is guided in the exclusion direction and is excluded to the trash can 110. In the retracted mode, as shown in FIG. 13, since the upper end 7301 of the curved surface portion 7311 is located slightly below the cutting position H, the sheet piece generated by cutting is located in the downstream direction in the transport direction along the upper surface portion 7312. Guided (ie in the non-exclusion direction). The cutting position H is a height position at which the upper rotary blade 71 and the lower rotary blade 72 rub against each other to perform cutting. In the exclusion mode, the seat guide 731 is located within the width direction range of the upper rotary blade 71 (that is, between the cut surface 711 and the non-cut surface 712), but in the retracted mode, the seat guide 731 is It is located slightly to the right of the upper rotary blade 71 in the width direction.

The left type slitter 7B has a symmetrical configuration with respect to the right type slitter 7A.

(effect)
According to the right type slitter 7A and the left type slitter 7B having the above configuration, the following effects can be exhibited.
(1) Due to the cantilever support, in the right type slitter 7A, the upper rotary blade 71 is located at the right end of the upper housing 75, and the lower rotary blade 72 is located near the right end of the lower housing 76. Then, since the upper rotary blade 71 is located at the left end of the upper housing 75 and the lower rotary blade 72 is located near the left end of the lower housing 76, as shown in FIG. 17, the upper rotary blade 71 is not cut. Both slitters 7A and 7B can be brought into close contact with each other so that the surfaces 712 face each other, and the width dimension of the sheet piece that can be cut in that case can be set to a very small dimension D1. Specifically, D1 is 5 mm.

Further, as shown in FIG. 18, the right type slitters 7A can be brought into close contact with each other, and as shown in FIG. 19, the left type slitters 7B can be brought into close contact with each other, and in these cases, cutting is possible. The width dimension of the sheet piece can be set to dimension D2. Specifically, D2 is 25 mm.

Further, as shown in FIG. 20, both slitters 7A and 7B can be brought into close contact with each other in the opposite directions to those in FIG. 17, and the width dimension of the sheet piece that can be cut in that case can be set to the dimension D3. Specifically, D3 is 48 mm.

Moreover, according to the combination and arrangement of the slitters shown in FIGS. 17 to 20, the width dimensions D1, D2, and D3 can be enlarged by pulling the two slitters apart.

Therefore, according to the right-type slitter 7A and the left-type slitter 7B having the above configuration, the width dimension of the sheet piece generated by cutting can be made very small and can be freely set.

(2) The first side surface 751 of the upper housing 75 does not project in the direction X1 on the non-cutting surface 712 side of the non-cutting surface 712, and is located on the non-cutting surface 712 side of the cutting surface 711. Therefore, the upper rotary blade 71 is not exposed from the upper housing 75 in the width direction. Therefore, in the right type slitter 7A and the left type slitter 7B, it is possible to prevent the operator from being damaged by the upper rotary blade 71.

(3) Since the sheet guide 731 of the cutting waste removing member 73 can be switched between the removing mode and the retracting mode, the right type slitter 7A and the left type slitter 7B are not only at the cutting processing position where the sheet piece needs to be removed. , Can be used even in the cutting position where it is not necessary to remove the sheet piece.

[Second Embodiment]
The slitter of the present embodiment is different from the first embodiment only in that the bleeding waste removing member is displaced in three modes.

FIG. 21 is a perspective view of the right-type slitter 7A of the present embodiment as viewed from slightly above on the upstream side. Here, the right-type slitter 7A is shown, but the left-type slitter 7B is exactly the same except that it is symmetrical with respect to the right-type slitter 7A. 22 to 25 are four views of the right type slitter 7A, FIG. 22 is a right side view, FIG. 23 is a front view seen from the upstream side, FIG. 24 is a rear view, and FIG. 25 is a rear view. It is a bottom view. In the right-type slitter 7A of the present embodiment, the seat guide 731 shows the first exclusion mode shown in FIGS. 21 and 22, the second exclusion mode shown in FIGS. 26 and 27, and FIGS. 28 and 29. It is possible to displace in the retracted mode.

In the right-type slitter 7A, the hole portion 7320 of the operation plate 732 has a first groove portion 7325, a second groove portion 7326, and a third groove portion 7327 for fixing the lever portion 7313, as shown in FIG. There is. Then, when the lever portion 7313 is fixed to the first groove portion 7325 as shown in FIG. 30, the seat guide 731 is in the first exclusion mode, and the lever portion 7313 is attached to the second groove portion 7326 as shown in FIG. When fixed, it is in the second exclusion mode, and when the lever portion 7313 is fixed in the third groove portion 7327 as shown in FIG. 32, it is in the retracted mode. The lever portion 7313 is urged toward the first groove portion 7325, the second groove portion 7326, and the third groove portion 7327 by a spring (not shown).

In the first exclusion mode, as shown in FIG. 22, since the upper end 7301 of the curved surface portion 7311 is located slightly above the cutting position H, the sheet piece generated by cutting is guided downward along the curved surface portion 7311. That is, it is guided in the exclusion direction and is excluded to the trash can 110. Also in the second exclusion mode, as shown in FIG. 27, since the upper end 7301 of the curved surface portion 7311 is located slightly above the cutting position H, the sheet piece generated by cutting is guided downward along the curved surface portion 7311. That is, it is guided in the exclusion direction and is excluded to the trash can 110. In the first exclusion mode, the sheet guide 731 is located within the width direction range of the upper rotary blade 71 (that is, between the cut surface 711 and the non-cut surface 712), but in the second exclusion mode, the sheet The guide 731 is located slightly to the right of the upper rotary blade 71 in the width direction. Therefore, according to the first exclusion mode, the sheet piece having a small width dimension can be reliably eliminated, and according to the second exclusion mode, the sheet piece having a large width dimension can be smoothly removed. In the retracted mode, as shown in FIG. 29, since the upper end 7301 of the curved surface portion 7311 is located slightly below the cutting position H, the sheet piece generated by cutting is located downstream in the transport direction along the upper surface portion 7312 ( That is, it is guided (in the non-exclusion direction). In the retracted mode, the seat guide 731 is located on the right side in the width direction as compared with the case of the second exclusion mode.

Other configurations of the right-type slitter 7A of the present embodiment are the same as those of the right-type slitter 7A of the first embodiment.

[Third Embodiment]
The slitter of the present embodiment is different from the slitter of the first or second embodiment only in that it further includes a bleeding waste removing auxiliary member.

FIG. 33 is a perspective view of the right-type slitter 7A of the present embodiment as viewed from slightly above on the upstream side. Here, the right-type slitter 7A is shown, but the left-type slitter 7B is exactly the same except that it is symmetrical with respect to the right-type slitter 7A. FIG. 34 is a right side view of the right type slitter 7A. FIG. 35 is a perspective view of the right-type slitter 7A viewed from slightly above on the downstream side in the transport direction. The bleeding waste removing auxiliary member 735 has a curved plate portion 7351 and a mounting plate portion 7352. The curved plate portion 7351 is located on the right side in the width direction with respect to the bleed waste removing member 73. As shown in FIG. 34, the curved plate portion 7351 has a tip portion 7350 at a position upstream of the cutting position K and above the cutting position H, and from the position of the tip portion 7350, the curved plate portion 7351 has a tip portion 7350. While maintaining a position higher than the cutting position H, it extends downstream from the cutting position K in the transport direction, and further curves downward and extends. The bleeding waste removing auxiliary member 735 is attached to the right type slitter 7A by fixing the attachment plate portion 7352 to the side surface 761 on the downstream side of the lower housing 76 of the right type slitter 7A with screws 7353. Since the screw 7353 can be released, the bleeding waste removing auxiliary member 735 is removable with respect to the right type slitter 7A.

According to the right-type slitter 7A having the above configuration, a large sheet piece generated on the right side in the width direction by cutting can be reliably removed downward as bleeding waste.

[Fourth Embodiment]
The slitter of the present embodiment is different from the slitter of the first to third embodiments only in that the displacement of the seat guide of the bleed waste removing member is linear rather than stepwise.

FIG. 36 is a bottom view of the right type slitter 7A of the present embodiment. Here, the right-type slitter 7A is shown, but the left-type slitter 7B is exactly the same except that it is symmetrical with respect to the right-type slitter 7A. In the present embodiment, the hole portion 7320 of the operation plate 732 has a first groove portion 7328 and a second groove portion 7329. The seat guide 731 is in the exclusion mode when the lever portion 7313 is fixed to the first groove portion 7328, and is in the retracted mode when the lever portion 7313 is fixed to the second groove portion 7329. The lever portion 7313 is urged toward the first groove portion 7328 and the second groove portion 7329 by a spring (not shown).

Further, in the present embodiment, the first groove portion 7328 is formed to be wide, and the lever portion 7313 can slide in the first groove portion 7328 in the width direction, and is at an arbitrary position in the first groove portion 7328 in the width direction. It can be fixed to. Therefore, the seat guide 731 can take a linearly displaced exclusion mode by moving the lever portion 7313 in the first groove portion 7328 in the width direction.

According to the right-type slitter 7A of the present embodiment, the exclusion mode of the seat guide 731 is set to the right side in the width direction from the position within the width direction range of the upper rotary blade 71 (that is, between the cut surface 711 and the non-cutting surface 712). It can be set to any position up to the predetermined position of. Therefore, not only a narrow sheet piece but also a slightly wide sheet piece can be smoothly removed as bleeding waste.

[Another Embodiment]
The following modified configuration may be adopted.
(1) The cantilever support of the rotary blade in the slitter may be only the upper rotary blade 71 or only the lower rotary blade 72. That is, the upper rotary blade 71 may be cantilevered and supported by the cantilever support portion, and the lower rotary blade 72 may be cantilevered and supported by the double-sided support portion, or the lower rotary blade 72 may be cantilevered and supported by the cantilever support portion. Then, the upper rotary blade 71 may be supported by the double-sided support portion.

Further, in that case, it is preferable that the double-sided support portion includes an inclination adjusting portion for adjusting the inclination of the axial center of the rotating shaft that supports the rotary blade. For example, in the right-type slitter 7A shown in FIG. 37, the upper rotary blade 71 is cantilevered and supported by the cantilever support portion 78 as in the first embodiment, and the lower rotary blade 72 is the right end of the lower housing 76. It is located in the vicinity and is supported by the double-sided support portion 80. The upper rotary blade 71 is rotationally driven, and the lower rotary blade 72 is driven by the rotation of the upper rotary blade 71. The double-sided support portion 80 includes a tilt adjusting portion that adjusts the tilt of the axial center 7421 of the rotating shaft 742 that supports the lower rotary blade 72.

Specifically, the lower rotary blade 72 is supported by the rotary shaft 742 via two bearings 811 and 812 arranged at intervals. The right end 7422 of the rotating shaft 742 is held by the fixed plate 802 via the bearing 801 and the left end 7423 is held by the movable plate 803. The fixed plate 802 is integrated with the right side surface of the lower housing 76, and the movable plate 803 is attached to the left side surface of the lower housing 76. As a result, the lower rotary blade 72 is supported by both sides in the lower housing 76. Then, by moving the movable plate 803, the inclination of the axial center 7421 of the rotating shaft 742 can be adjusted. That is, the movable plate 803 constitutes an inclination adjusting portion.

FIG. 38 is a perspective view of the right type slitter 7A of FIG. 37. FIG. 39 is a perspective view of the movable plate 803. The movable plate 803 includes a main body 804 along the left side surface of the lower housing 76 and a veneer 805 parallel to the front surface of the lower housing 76. The movable plate 803 is fixed to the lower housing 76 by two screws 8031. Each screw 8031 inserts a mounting hole 8041 of the main body 804. The mounting hole 8041 has a larger diameter in the vertical and front-rear directions than the rod (shaft portion) of the screw 8031. The left end 7423 of the rotating shaft 742 is fitted in the mounting hole 8042 of the main body 804.

Then, the inclination adjustment by moving the movable plate 803 is performed as follows. Note that FIG. 40 is a schematic view of the lower housing 76 of the right-type slitter 7A as viewed from above, and FIG. 41 is a schematic view of the right-type slitter 7A as viewed from the front side.

(I) When the screw 8031 is loosened to move the movable plate 803 forward and then the screw 8031 is tightened to fix the movable plate 803, as shown in FIG. 40, the axial center 7421 of the rotating shaft 742 is the chain line A. The lower rotary blade 72 is tilted like the chain wire C. Alternatively, when the screw 8031 is loosened to move the movable plate 803 in the rear direction and then the screw 8031 is tightened to fix the movable plate 803, as shown in FIG. 40, the axial center 7421 of the rotating shaft 742 is the chain line B. The lower rotary blade 72 is tilted like the chain line D.

When moving the movable plate 803 in the front-rear direction, the movable plate 803 can be moved along the horizontal plate 810 whose upper end is horizontal, so that the movable plate 803 can be moved stably. Further, since a screw screwed into the lower housing 76 is provided on the rear side of the hole 8051 of the veneer 805, the head 8033 of the screw is set to a desired moving position in the front-rear direction, and the veneer 805 is set. By moving the movable plate 803 so that the head 8033 is flush with the head 8033, the movable plate 803 can be moved accurately.

(Ii) When the screw 8031 is loosened to move the movable plate 803 upward and then the screw 8031 is tightened to fix the movable plate 803, as shown in FIG. 41, the axial center 7421 of the rotating shaft 742 is the chain line E. The lower rotary blade 72 is tilted like the chain line G. Alternatively, when the screw 8031 is loosened to move the movable plate 803 downward and then the screw 8031 is tightened to fix the movable plate 803, as shown in FIG. 41, the axial center 7421 of the rotating shaft 742 is the chain line F. The lower rotary blade 72 is tilted like the chain line H.

Although the above description is based on the right-type slitter 7A, the left-type slitter 7B is exactly the same except that it is symmetrical with respect to the right-type slitter 7A.

As described above, by moving the movable plate 803 back and forth and up and down, the inclination of the lower rotary blade 72 can be changed in various ways, whereby the following effects can be exhibited.

(A) Since the contact of the lower rotary blade 72 with respect to the upper rotary blade 71 can be adjusted, a state of the rotary blade capable of satisfactorily cutting the sheet can be realized.

(B) By adjusting the inclination of the lower rotary blade 72 in the front-rear direction as in (i) above, the durability of both rotary blades can be improved. In particular, the durability of both rotary blades can be further improved by adjusting so that both rotary blades are parallel to each other.

(C) By tilting the axial center 7421 of the lower rotary blade 72 upward (like the chain wire E) as in (ii) above, a slitter capable of improving the discharge of bleeding chips can be realized. That is, as shown in FIG. 42, the right-type slitter 7A and the left-type slitter 7B in which the axial center 7421 of the lower rotary blade 72 is tilted like the chain line E are opposed to the non-cutting cross section 712 of the upper rotary blade 71. When arranged in close contact with each other, the bleeding chips generated between the slitters 7A and 7B are smoothly lowered because the lower rotary blades 72 of the slitters 7A and 7B are tilted so as to spread downward. Is discharged to.

(D) Since the inclination of the lower rotary blade 72 located inside the upper rotary blade 71 in the width direction in the housings 75 and 76 is adjusted, as shown in FIG. 42, the right type slitter 7A And when the left type slitter 7B is arranged in close contact with the non-cutting surface 712 of the upper rotary blade 71 so as to face each other, the tilted lower rotary blade 72 does not interfere with each other. Therefore, it is possible to generate a sheet piece having a very small width dimension as shown in D1 (FIG. 17) by cutting without any trouble. In the housing, the "inside in the width direction" is the side close to the center of the housing, and the "outside in the width direction" is the side close to the side surface of the housing.

In the example of FIG. 37, the lower rotary blade 72 is supported by both sides, but the upper rotary blade 71 may be supported by both sides. However, in that case, the upper rotary blade 71 is arranged inside the housings 75 and 76 in the width direction with respect to the lower rotary blade 72. According to such an arrangement configuration, when the right type slitter 7A and the left type slitter 7B are arranged in close contact with each other so that the non-cutting surfaces 722 of the lower rotary blade 72 face each other, the same as in each of the above embodiments. Sheet pieces with very small width dimensions can be produced by cutting.

Further, the inclination adjustment of the rotary blade as described above is performed so as to be in a predetermined reference state at the factory shipping stage, and normally, subsequent adjustment is unnecessary. However, the cutting performance may be poor due to the type of sheet or the degree of wear of the rotary blade. In such a case, if necessary, the serviceman or the user can adjust the inclination of the rotary blade so that good cutting performance can be obtained.

(2) The slitter does not necessarily have to be provided with a bleeding waste removing member.

(3) The rotary shaft 741 is not limited to a hollow member, but may be a solid member or a member formed by appropriately combining them, as long as the upper rotary blade 71 can be rotatably supported. The same applies to the rotating shaft 742.

(4) As shown in FIG. 43, the left-right positional relationship between the upper rotary blade 71 and the lower rotary blade 72 may be exchanged. That is, in the right-type slitter 7A, the upper rotary blade 71 is located near the right end of the upper housing 75, and is cantilevered supported by the cantilever support portion 78 on the non-cutting surface 712 side of the upper rotary blade 71. .. Further, the lower rotary blade 72 is located at the right end of the lower housing 76, and is cantilevered supported by the cantilever support portion 79 on the cut surface 721 side of the lower rotary blade 72. The lower rotary blade 72 is located on the right side of the upper rotary blade 71. When the bleeding waste removing member (not shown) or the bleeding waste removing auxiliary member (not shown) is provided, it may be provided on the cutting surface 711 side (that is, the right side of the cutting surface 711) of the upper rotary blade 71. .. The left type slitter 7B has a symmetrical structure with the right type slitter 7A.

(5) The slitter may include a sheet transport assisting member that assists in transporting the sheet piece generated by cutting downstream in the transport direction. FIG. 44 is a perspective view of the right type slitter 7A provided with the sheet transport assisting member 8. FIG. 45 is a right side view of the right type slitter 7A of FIG. 44. Here, the right-type slitter 7A is shown, but the left-type slitter 7B also has exactly the same basic structure except that it is symmetrical with respect to the right-type slitter 7A. The seat transport assisting member 8 includes a transport assist guide 81, two slide pins 82, and a spring 84. The transport assist guide 81 has a guide surface 811 on the upper edge, which is in contact with the back surface of the sheet piece and guides the sheet piece. The two slide pins 82 are provided so as to be slidable in the width direction with respect to the lower housing 76. The transport assist guide 81 is supported at the right end of the slide pin 82. As a result, the transport auxiliary guide 81 comes into contact with the sheet piece within the width direction range of the upper rotary blade 71 (that is, between the cut surface 711 and the non-cut surface 712) by sliding the slide pin 82. It is possible to move between the auxiliary position and the second transport auxiliary position that contacts the sheet piece on the non-cutting surface 712 side of the upper rotary blade 71 on the non-cutting surface 712 side. The spring 84 is provided in the lower housing 76 so as to urge the transport auxiliary guide 81 in the direction X1 on the non-cutting surface 712 side of the upper rotary blade 71.

In the right-type slitter 7A having the above configuration, when the slitters adjacent to the right side are arranged close to each other, the transport assist guide 81 in contact with the slitter is moved to the lower housing 76 side and is located, and the slitter is located. When they are arranged apart from each other, the transport assisting guide 81 is moved and positioned in the direction X1.

According to the sheet transport assisting member 8 having the above configuration, the sheet transport assisting guide 81 can guide the sheet piece downstream in the transporting direction regardless of the position of the slitter adjacent to the right side. Therefore, according to the right-type slitter 7A having the above configuration, it is possible to smoothly cut the sheet and convey the sheet piece.

(6) The connecting plate 77 may be used to adjust the amount of lap Q between the upper rotary blade 71 and the lower rotary blade 72 as shown in FIG. 46. The lap amount is the vertical dimension of the overlapping portion between the cutting edge of the upper rotary blade 71 and the cutting edge of the lower rotary blade 72. FIG. 47 is a perspective view of the connecting plate 77. The connecting plate 77 is provided, for example, as shown in FIGS. 21, 22, and 24. That is, the connecting plate 77 has two mounting holes 772 at the upper portion and two mounting holes 773 at the lower portion. The connecting plate 77 is fixed to the upper housing 75 by a screw 775 that inserts the mounting hole 772, and is fixed to the lower housing 76 by a screw 776 that inserts the mounting hole 773. The mounting hole 773 has a diameter larger than that of the rod (shaft portion) of the screw 776. Then, in order to adjust the wrap amount, the screw 776 may be loosened, the lower housing 76 may be moved up or down with respect to the connecting plate 77 so as to obtain a desired wrap amount, and then the screw 776 may be tightened. .. Since the amount of wrap can be adjusted by the connecting plate 77 in this way, the optimum cutting state can be appropriately realized.

The connecting plate 77 is configured so that when the upper rotary blade 71 is driven to rotate, the lap amount can be adjusted by loosening the screw 775 for attaching to the upper housing 75, and the lower rotary blade 72 is driven to rotate. In some cases, the wrap amount can be adjusted by loosening the screw 776 for attaching to the lower housing 76.

Further, the adjustment of the lap amount as described above is performed so as to be in a predetermined reference state at the factory shipping stage, and normally, subsequent adjustment is unnecessary. However, the cutting performance may be poor due to the type of sheet or the degree of wear of the rotary blade. In such a case, if necessary, the serviceman or the user can adjust the amount of wrap so that good cutting performance can be obtained.
